This invention relates to stock quotation tickers in general and more especially to means for protecting the stock quotation ticker from injury from tape pullin devices which are generall used with stoc quotation rejecting machines.

When tape pulling devices are used for taking up the tape as it is discharged from the ticker, care must be taken that the tension exercised by the tape puller is properly controlled so that it will give suificient tension when the printing wheel is in engagement with the tape or the ticker is at rest to throw the printing wheel or other mecha- 16 nism of the ticker out of alinement. To this end, the present invention aims to provide a device for positively locking the tape from being pulled by the tape pulling device whenever the ticker is at rest.

Specifically, the present invention still further aims to provide a tape locking means which is controlled by one of the magnets of the ticker whereby the locking device is released whenever the magnet is energized during the transmission of a message, and which is permitted to lock the tape from being pulled by the tape puller whenever such magnet is de-energized during the time when the ticker is at rest.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawings in which Figure 1 is a side elevation showing the present improvement attached to a ticker, the ticker being illustrated diagrammatically;

Fig. 2 is a fragmental section on the line 2-2 of Fig. 1; and

Fig. 3 illustrates diagrammatically the combination of a ticker, projecting machine and tape pulling device.

In the embodiment shown, the ticker 1 is provided with the usual presser arm 2 which is pivoted by means of the screw 3 to the ticker housing 1 at the front end of the ticker, the rear end of the presser arm 2 being connected by the spring 4 with the abutment screw 5.

The tape T passes adjacent to the presser arm 2 over the discharge bracket 6 to the projecti machine 7 and :then tothe tape puller P. o the resserarm2ithere is secured a spring 8 having its front straight end clamped against the .presser arm 2by the 5 plate 9 and its rear end curved downwardly to form the loop 10, having ta cum-ed finger portion 11 adapted to engage the tape T as it passes over the disc'har e block :6 and to press the tape T into leasing engagement with the discharge block "6 when the ipresser arm is released and pulled downwardly by the spring 4. To the side ofthe Presser arm 2 there is, provided an armature 12 adapted to be attracted bythe magnet 13,'in turn to raise the presser arm 2 upwardly about its pivot point 3 when the magnet 13 is energized.

The magnet 13 forms a part of the ticker mechanism 1 and is energized whenever :a message is transmitted by the ticker. it is so energized by other mechanism not shown, the tape T isadvanced as theimessage is recorded on the tape 'T. While it being so advanced, the tape puller P is operably connected to take up the tape T asit issodischarged and pull it through the projector -7. The tape T, in the present instance, :is free to he pulled by the tape; 'uller P whenever a messa e is transmitted as to the tent that at suc time the resser arm 2 is raised and consequently the friction finger 11 in turn also raised sutliciently to permit the tape T freely to pass over the discharge bloe'kfi.

It will also appear that since the ticker feeding action of the tape T always "takes place after the printing action, and the lever 2 is only elevated by the magnet 13 the printing action and released before the succeeding ticker feeding action, the fingerll will have engaged the tape T during the ticker feeding action to thereby iron out the vibrations transmittedtothe tape during this ticker feeding action and thus prevent "the transmission of such vibrations to the portion of the tape in the projecting machine.

Furthermore, as will appear from Fig. 1, when the finger 11 impinges the tape against the abutment 6, slack is formed in the tape before the tape reaches the abutment 6, so that the vibrations transmitted to the tape by the ticker feeding action will be taken up in such slack and dissipated'by the finger 11 and abutment 6 to prevent such vibrations being transmitted Cb the portion of the tape lo cated in the projector 7. Such slack also forms a reserve to permit the tape being pressed intoengagement with the printing mechanism, not shown, so that the pulling action of the tape puller will then merely take up the slack during the printing action without exercising any pulling force on the printin mechanism.

t is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
